WDR - wide dynamic rageMore

Digitally adjusting exposure in areas of the frame to maintain optimum detail in both the shadows and highlights of the image.

CIR - Committed Information RateMore

Committed information rate or CIR in a Frame relay network is the average bandwidth for a virtual circuit guaranteed by an ISP to work under normal conditions. At any given time, the bandwidth should not fall below this committed figure. The bandwidth is usually expressed in kilobits per second (kbit/s).

DNR - digital noise reductionMore

Image noise is interference in the video signal that shows up as grainy specks. It can be caused by low lighting situations, a nearby power interference, heat, or device algorithms.

DNR is a technique of removing image noise from a video signal by applying a digital comb filter. It makes images clearer and reduces video file size.

A 2D filter reduces the noise that can be found in low light images. This type of filter is sometimes confused by motion, resulting in blur trails.

A 3D filter goes one step farther and effectively reduces the noise in static images and images with movement.

ATR - adaptive tone reproductionMore

Sony's ATR/ATR-EX (Adaptive Tone Reproduction) function provides gradation compensation to improve the contrast of subjects whose gradation has been lost in cases where, for instance, both low-luminance areas and high-luminance areas exist in the same picture.

The ATR function improves the visibility of the entire picture by providing the optimum gradation compensation for the image in one field based on the luminance information.

Day / NightMore

A Day/Night function helps the camera adapt to low lighting conditions on cameras that are not equipped with Infrared illuminators.The Day/Night function can be done by using a mechanical cut filter (sometimes called an IR cut filter or ICR) and/or by using dual imagers (one color, one black & white).

ICR - Infrared Cutfilter RemovalMore

The IR cut filter is on when the camera is operating as a color camera for precise color reproduction. With ICR, the filter is removed which allows for much greater light sensitivity in monochrome mode.

HLC - high light controlMore

HLC is the masking of a very intense light source such as car headlights in order to bring up detail in the normally lit areas, such as a license plate or face.

BLC - back light compensationMore

In images where a bright light source is behind the subject of interest, the subject would normally appear in silhouette. BLC allows the camera to adjust the exposure of the entire image to properly expose the subject in the foreground. WDR is a more effective alternative to BLC because it handles multiple exposure zones to give both the highlight and low light areas a proper exposure.
